A typical American living room of a New England home. Its occupants have changed over the century. In the 1950s, a boy named Richard was born here. This room is where he spent his childhood and adolescence, where he finishes school, and where he brings his fiancée Margaret. The young family has children, all the happiest moments of their lives take place here, and the sad ones here too. The children have grandchildren, and Richard and Margaret begin to realize that their time is passing.
